'2 Claims. 1

The present invention relates to improvements in a beater. It consists of the combinations, constructions and arrangements of parts as hereinafter described and claimed.

An object of my invention is to provide a beater in which all of the parts may be quickly disassembled for cleaning purposes. The parts can be disassembled and assembled without the necessity of using any tools. The beating elements are positively rotated in opposite directions and the device is simple in construction.

A further object of my invention is to provide a device of the type described in which the beating elements rotate about a central stem that extends to the center of a handle and therefore a direct axial thrust from the handle to the beating elements is provided when using the device. A large driving gear meshes with two small bevel gears that operate the beating elements and the two small gears mesh with the large gear at diametrically opposite points and act as bearing supports for the large gear to equalize pressures and prevent any wobbling of the large gear during its rotation. This construction results in a smoother operating device and wear is reduced to a minimum. A novel catch mechanism is used for holding the parts in assembled relation. 7

Others objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which:

Figure 1 is a vertical section through the device, portions being shown in elevation for clarity;

Figure 2 is a side elevation of the device;

Figure 3 is an enlarged perspective view illustrating the top of the tubular shaft;

Figure 4 is an enlarged horizontal section taken along the line IVIV of Figure 1;

Figure 5 is an enlarged horizontal section taken along the line VV of Figure 1;

Figure 6 is a horizontal section taken along the line VI-VI of Figure 1; and

Figure 7 is a horizontal section taken along the line VIIVII of Figure 1.

- While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit and scope of the invention.

In carrying out my invention I provide a frame indicated generally at A and this frame has a bore l for receivingthe top of a stem B. The

frame can be a casting or it can be a stamping, if desired. The frame has an offset portion 2 extending from one side of a shoulder 3 in which.

ring 6 that is slidably received in an opening 1 provided in the offset portion 2. A leaf spring 8 has one end secured tothering 1 and its other end secured to the offset portion 2. The leaf spring will tend to move the ring to the right in Figure l, for causing it to enter the notch 5 and hold the stem against removal. A button 9 is carried by the free end of the leaf spring and when this button is manually depressed, the ring 6 will move and will free the stem B so that it can be removed from the frame A.

The frame also has a second offset portion [0 extending beyond the fork 4 and this portion has a bearing H for rotatably receiving a hand crank l2. The crank carries a large bevel gear l3 and this gear meshes with two small bevel gears l4 and it which in turn are connected to beating members 0 and D, respectively. I will describe the structure of the beating member C and then will set forth the structure of the beating member .D.

It will be seen from Figure 1 that a hollow shaft [6 is slipped over the stem 13 and Figure 3 shows the top of this hollow shaft as being provided with diametrically opposed prongs ll. Figure 5 shows the undersurface of the small bevel gear 14 on an enlarged scale and the under surface of this gear has a pair of diametrically opposed recesses 18 for receiving the prongs IT. The gear I4 has a central bore IQ for rotatably receiving the stem B and the gear spaces the hollow shart H5 from the stem. The follow shaft in turn supports the gear l4 so that it will rotate against the under side of the fork 4. The hollow disc 22. Figure 6 shows the beating member C as having four arms 23. In actual construction, the four arms are formed from two elongated strips that are looped in the manner shown and extend at right angles to each other. At the point where the strips cross each other, aligned openings 24 are provided and the stem B extends through these openings. The free ends of the. strips are secured to the disc 22. I do not wish to be confined to any particular number of arms, because the number can be changed to suit the desired purpose.

The lower bevel gear rotates on the enlarged portion of the shaft [6 and carries the beating member D. The member D is formed from a single strip 25 and this strip has a central open fit therewith. The end 28 of the sleeve acts as a bearing support for the beating member C. The stem B has a head 29 which is larger in diameter than the sleeve 21 and therefore the beating member D will rest on the upper surface of the head. In this way the two beating members are spaced from each other and can rotate in opposite directions. The beating member D will support the gear l5 at the right position for causing it to mesh with the driving gear 13.

The handle E' is composed of two hand grip portions 30 and these are secured to the frame A by a bolt 3! or other suitable fastening means. The hand grip portions project equal distances from the frame so that a grasping of the handle will cause the force to pass along the axis of the stem B from the handle to the beating members during the operation of the device. It will be seen from Figure 1 that the frame A has an extension 32 that depends from the offset I0 and the extension 32 has an inwardly turned portion r 33 for underlying the bevel gear l5.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

Inassembling the parts, the reduced portion of the hollow shaft I8 is first passed through the bore 2| of the gear 15- and then the gear [4 is mounted on the pronged end of the shaft. The bores. 24 of the beating member 0' and the bore 261 of the beating member D are then aligned with each other and the stem B is movedthrough the aligned bores and through the bore 19 of the gear M. When the beating member D rests on the head 29 and the beating member C rests on the sleeve 27', the stem B will extend the required distance above the gear 14. The assembled beating members and stem can then be applied to the frame A, care being taken that the stem is threaded through the locking ring 6 and is then moved into the bore l, and the fork 4. The notch. 5 must face away from the offset portion 2 and the button 9 must be held depressed until the stem enters the ring. When the stem is seated-in thev bore l, the button 9 is released and this will permit the leaf spring to move the ring into the notch for looking all of the parts together.

The device can now be operated in the usual manner by turning the crank [2 with one hand and holding. the handle E with the other hand.

In actual construction a sleeve is.

The gear will drive the beating members in opposite directions. After use the parts can be disassembled by merely pressing on the knob 9 for freeing the stem from the frame. The stem can then be freed from the beating members, after which the beating member C can be removed from the beating member D. The purpose of the reduced portion on the hollow shaft I6 is to permit the shaft to be swung angularly to extend at a slight angle to the axis of the member D when moving the shaft through the bore of the gear [5 either in assembling or disassembling the parts. When the member C is received in the member D, the enlarged portion of the shaft IE will enter the gear bore'2i. larged portion 20.

I claim:

1. In combination, a frame with a handle and having a bore and a fork-shaped portion registering with the bore, a stem having one end remcvably receivable in the bore and its other end provided with a pair of stepped shoulders, the stem when received in the bore also being engaged by the fork, means for removably securing the stem to the frame, a beating member rotatably mounted on the stem and having one end bearing on one of the shoulders, a gear and tubular shaft disposed at the otherend of the member, a second beating member rotatably mounted on the stem and having one end bearing on the other shoulder and a gear mounted at the other end and rotatable on the tubular shaft,

The gear [5 rotates on the ena driving gear in mesh with the two other gears,

and a crank carried by the frame and connected to the driving gear for rotating it.

2. In a device of the type described, a stem having a pair of stepped shoulders spaced apart, a beating member rotatable about the stem and having one end bearing against one of the shoulders, the other end of the member having an.

integral hollow shaft with an enlarged outer cylindrical portion disposed near the member, the other end of the shaft having projections, a gear rotatably mounted on the stem and having recesses for receiving the projections, a second beating member rotatable about the stem and having one end bearing against the other shoulder, a

second gear mounted on the other end of the second, member and being rotatably carried by the enlarged cylindrical end of the shaft, and a driving gear meshing with the other two gears for rotating them and their beating members in opposite directions,
